SDN offers a centralized view of the network, giving an SDN Controller the ability to act as the “brains” of the network. The SDN Controller relays information to switches and routers via southbound APIs, and to the applications with northbound APIs. One of the most well-known protocols used by SDN Controllers is OpenFlow, however, it isn’t the only SDN standard, despite some using “SDN” and “OpenFlow” interchangeably.

Centralized, programmable SDN environments can easily adjust to the rapidly changing needs of businesses. SDN can lower costs and limit wasteful provisioning, as well as provide flexibility and innovation for networks.
